CROSS-OVER SWITCH.

SPECIFICATION forming part of Letters Patent No. 332,641, dated December15,1885.

Application filed February 24, 1885. Serial No. 156,876. (No model.)

To all whom it may concern:

Be it known that I, NEVIN CORT, a citizen of the United States, residingat New Florence, in the county of WVestmoreland and State ofPennsylvania, have invented a new and useful Cross-Over Switch for theuse of Railroads, of which the following is a specification.

My invention relates to an improvement in cross-over switches for theuse of railroads; and it consists in a device to make cars pass from onemain track to another parallel with it without breaking the main linesand with out the use of frogs by the operation of a lever on a tumblingshaft or rod that controls or moves the switch on or away from the mainlines, as will be fully described hereinafter.

The accompanying drawings represent my invention.

Figure 1 represents a plan of the switch and track; Fig. 2, a sideelevation of joints; Fig. 3, aperspective View of parts 3; Fig; 4, aperspective View of parts 4; Fig. 5, a perspective view of parts 1 and5.

A A represent two tracks of a main line of a railroad parallel to eachother with the usual distance of six feet between them. B is a switchthat extends diagonally from one track to the other. Both ends of theswitch are alike. The receiving-points a of the switch at the side firstencountered by the wheels of an engine or car are about three feet inadvance of the opposite side, and gradually rising from a to b, to carrya train onto the switch from one main track to the other. The surface ofthe switch is level and at a height to prevent a contact of wheels withthe underlying main track. The two sides of the switch, each composed offive pieces, 1 2 3 4 5, are alike, and the pieces 1 and 5, opposite toeach other, are held together by rods d, by which they aresimultaneously drawn The pieces 1 are at the outside of the inner railof the main track, and the pieces 5 near the inside of the outer rail,both pivoted to the ties in a manner that their outer ends can be pushedover the rails of the main track or removed from it. The pieces 1 arepivoted to pieces 2, that extend diagonally over the space between thetwo tracks from one to the other, and are rendered immovable. To thepieces 2 are jointed the ends of shorter pieces 3, which pieces, leavingone end unattached, can be made to extend along the inner rails of themain lines, or to reach across them to join the pieces 4, by which theyare supported. The pieces 4, which serve as braces to the pieces 3 whenthe switch is completed, are fixed and form the continuation between thepieces 5 and 3. All joints by which the parts of the switch are heldtogether are half lap-joints. Between the two tracks of the main line,equidistant from both, is a lever or tumblingshaft, 0, of a length equalto that of the switch, and secured to the ties in a manner to be turnedupon its axis. On this shaft 0, between the pieces 2 of the switch, aretwo pins,

f, one on top and one underneath, that serve for the attachment of arms9 on double levers D, fulcrumed at p. The other arms, h, of the levers Dare pivoted at theinside of the pieces 3, so that by turning the shaft 0the free ends of pieces 3 are either pushed over the rails into therecesses on pieces 4 to close the switch or drawn away from it to leavethe main track open. At both ends of shaftQG: are pins n, placed on topand underneath, to which pins rods m are attached that are jointed tothe 3 outer ends of pieces 1, so that when the shaft 0 is turned theends of the switch are moved simultaneously with pieces 3 either on oroff the rails of the main line, and with them the pieces 5. The lever 12on the shaft 0 is for turning the switch on or away from the main line.

Having thus described my; invention, I claim- 1. The combination of thepartially-revolving shaft 0, rods m, connected to opposite ends thereof,the switch-rails 1 5, and connecting rods d, the ends of the rails 1being placed in advance of the ones 5, substantially as shown.

2. The combination of the main tracks A 53 and cross-over rails 24,extending acrossthem, with the shaft 0, rods on, rails l 5, and rods d,substantially as described.

3. The combination of the'fimaintracks A, the shaft 0, rods 9 h, leversD, and the switchrails 3, substantially as set forth.

4. The combination of the partially-revolving shaft 0, rods m, connectedto opposite ends the shaft 0, switch-railsl 5, connectedtogetherthereof, the switch-rails 1 5, connected together, and the cross-overrails 2 3 4, the rails 3 being connected to the shaft 0 so as to be 5moved at the same time as the ones 1 5, substantially as specified.

5. The combination of the main tracks A,

and to the shaft, the, rails 24 3, rods 9 h, and levers D, substantiallyas described.
